The orginal problem with this monitor was that it would "blink" off, and when it would come back on, the settings (size, position, etc.) would revert to presets (which are way off). I believe I found the cause for this (bad connetions in hv circuit). It now plays ok and the geometry settings stay put, but I can't adjust the grey scale which is too green on low lites. The customer menu has "color tuning" but this affects hilites (drives) only. Is there a service menu on this unit, and how do you gain access to it? Also, is it possible to change the preset geometry adjustments? I assume these are stored in an eeprom.
